Abstract

PURPOSE
The aim of this study was to analyze the influence on voiding symptoms when performing sling operation on patients with stress urinary incontinence with detrusor underactivity.
MATERIALS AND METHODS
We analyzed medical records of 100 patients who received the sling operation. Based on their preoperative urodynamic study, we defined "stress urinary incontinence with detrusor underactivity (SUI with DU)" group as these findings; peak flow less than 11 ml/s or void with abdominal pressure instead of detrusor contraction or residual urine volume more than 100 ml. And the others were defined as the "stress urinary incontinence only (SUI)"group. We compared two groups and analyzed the changes of pre- and postoperative uroflowmetry.
RESULTS
The number of patients with the "SUI with DU" group was 30 and that with the "SUI" group was 70. In the "SUI with DU" group, there were no changes in peak flow rate and residual urine volume between postoperative uroflowmetry and preoperative urodynamic study (15.1 +/- 7.9 vs. 14.7 +/- 7.1 ml/s, 123.1 +/- 79.2 vs. 127.3 +/- 91.9 ml) (p>0.05). Twenty four patients underwent urinary drainage with nelatone catheter either on postoperative first or second day. However, 22 patients did not need to continue self catheterization.
CONCLUSION
Sling operation could be performed on patients who are diagnosed as stress urinary incontinence with detrusor underactivity without aggravating their voiding symptoms.
